Anthurium caulorrhizum Sodiro

• Genus: Anthurium
• Botanical Background: Described by the botanist Sodiro, this species has contributed to our understanding of tropical understory plants and continues to intrigue both horticulturists and researchers.

• Geographical Range: Native to parts of Ecuador and neighboring regions, typically inhabiting tropical lowland and premontane rainforests.
• Environment: Thrives in warm, humid climates with well-draining, organic-rich soils and prefers shaded to partially shaded conditions.

Leaves

• Exhibits medium to large, elliptical
• Glossy finish
• Intricate venation, creating subtle patterning on a deep green background

Inflorescence (Spadix & Spathe)

• Features a modestly colored spathe—ranging from greenish to brownish—encasing a slender spadix
• Flowers emit a mild scent
• Rely on insect pollinators

Growth Habit

• This terrestrial species is characterized by its caulorrhizous growth, producing elongated rhizomes that spread across the substrate

Light Requirements

• Does best in bright, indirect light that preserves its vibrant foliage without exposing it to harsh direct sun

Watering & Humidity

• Regular watering is essential to maintain evenly moist soil
• Appreciates high humidity levels

Soil & Potting Mix

• A well-draining, peat-based mix enriched with organic matter to replicate its natural forest floor conditions

Temperature & Fertilizer

• Ideal temperatures range from 65°F to 80°F
• Feed with a balanced, diluted fertilizer during the growing season to promote steady growth

Division

• Dividing the rhizomes

Stem Cuttings (if applicable)

• Node cuttings can also yield new plants under proper conditions

Seeds

• While seeds can be used, they often exhibit variable germination rates and require a longer period to reach maturity

Typical Issues

• May encounter pests such as spider mites and mealybugs
• Root rot can occur if overwatered

Treatment Recommendations

• Manage infestations with insecticidal soap or neem oil
• Ensure adequate drainage to reduce the risk of fungal diseases

• Local folklore often celebrates its unusual stem and leaf combination, and its ecological role in the tropical understory adds to its allure
• Prized for its distinctive growth habit and detailed leaf structure

• A valued specimen in curated aroid collections

Wild Population Status

• Although detailed assessments are limited, its natural habitat is increasingly threatened by deforestation and environmental changes

Market Availability

• Remains rare in cultivation
• Typically sourced through specialized collectors or botanical institutions
